powerpc/64s: system reset interrupt preserve HSRRs Code that uses HSRR registers is not required to clear MSR[RI] by convention, however the system reset NMI itself may use HSRR registers (e.g., to call OPAL) and clobber them. Rather than introduce the requirement to clear RI in order to use HSRRs, have system reset interrupt save and restore HSRRs.
